At the time they were reasonable value for money compared with the competition and were pretty unique in that the set up was based on individual machines around a single motor. (Same as its small brother the K5). the original concept, which was the forerunner of the ck26, if I remember correctly, was that you selected the table ( ref 700) and then added the machines you required giving a set up selected specifically for your needs. There were a number of options such as band saw and grinder in addition to the usual functions.
You get what you pay for and Bob is right, the tilting table is a poor feature and the fences definately get in the way so you have to be very careful to plan your work to minimise that.
I don't know how many Kity sold in total but in my last 12 months (mid '80s), as manager of a small distributor, we sold upwards of 20 machines all to business users. Doesn't sound a lot but it was compared to our other sales. I recall that they also introduced a direct drive version of the machine (704 DD), so I can't remember what the split in sales was.
Both machines had a single 1.5kw / 2 hp motor but the DD (5 function) had an additional 1/2 hp motor driving the slot morticer.
Capacity of the C26 was: (in the late 80s ).
Saw - table = 400 x 550mm capacity 70mm depth. p/t - capacity 259 x 150 mm. moulder - spindle 30mm
List prices in late 80s was around: 704 DD @ £ 2800 and C26 @ £ 2200 including VAT and both 5 function (4 function was around £400 cheaper)

EDIT
Just had a quick look among my useful stuff (rubbish to everyone else ) and found some old price lists and even older brochure (1981) might be able to scan some if of any interest when I can find time. My prices weren't spot on but pretty damn close.
